Study Notes

Oxygenation and Respiratory System

Primary function of diffusion in the context of oxygenation: to facilitate the exchange of oxygen and carbon dioxide between the air we breathe and the blood.

Pulmonary Circulation

Main function of pulmonary circulation in the respiratory system: to transport deoxygenated blood from the heart to the lungs, and then return oxygen-rich blood from the lungs to the heart.

Hypoxemia

Definition of hypoxemia: a state of insufficient oxygen in the blood, characterized by low oxygen levels in the arterial blood.

Ventilation Regulation

Regulation of ventilation in the lungs: controlled by the respiratory center in the brain, which responds to changes in blood carbon dioxide levels and pH.

Alveolar Gas Exchange

Role of alveolar gas exchange in the respiratory process: to facilitate the exchange of oxygen and carbon dioxide between the air we breathe and the blood, allowing oxygen to enter the bloodstream and carbon dioxide to be removed.
